Gays Done. Freezes after 3-4 hours of play (in real time, not game time) (Days Gone)

I have a weak computer so to speak. "Green" GT1050TI, "green" set of mother / percent on Kaby Lake (G4560 + some kind of mother from Rock Ass), 16 hectares of RAM, "green" again hard Sea Gay 4 terabytes. And all this snot hangs on a very Chinese power supply unit (so Chinese that this company is not even on Aliexpress) with a capacity of as much as 400,000 Chinese watts (whoever remembers will understand. Or droppings). 400 watts in total And this art is great at high, but after 3-4 hours the drops begin from 45-50 Fps to 4-5. I cut the igruhu, cut it in again - everything is as it should be. I feel the iron - the cooler is cold, the vidyuha is cold, even the hard is cold. Only the chipset is hot, but if he was to blame, I would have sent him to Hell / sorry, if he was to blame, it would have been necessary to shut down the computer, cool it down, ToDaSyo (ToDaSyo is a great martial art). All in all,
PS: Why did I mention that everything was "green" - because in Kazakhstan, "green" hardware was then sold 1.5-2 times cheaper than usual, because the characteristics were slightly reduced. In the USA, the same iron cost, on the contrary, 1.5 times more expensive - because "green". 2015 or 16. And he already took hard for his power supply in 2020, also "green".
